LIQUID-FILTER.

' Specification of Letters Patent.

Patented May 2e, `1907;

:Application tiled September 15, 1906. Serial No. 334,814.

4N ew York, have invented anew and useful Improvement in Liquid-Filters, of which the following is a specification.

This invention relates to filters or strainers which are more particularly designed for removing impurities from gasolene before the same 1s delivered to gas engines.

The object of this invention is to produce a filter or strainer for this purpose which is` comparatively simple in construction,wliich has a large capacity and not liable to become inoperative and which can be readily cleaned when necessary. In the accompanying drawings: Figure 1 is a vertical longitudinal section of my improved iilter or strainer. Fig. 2 is .a horizontal section thereof 'in line 2 2 Fig. 1.

Similar letters of reference indicate correspending parts in both figures.

4A represents the hollow body or separating chamber of the iilter or strainer which preferably has a semi-spherical body a and a removable cover a) which normally closes an opening in the top of the chamber which is of a diameter equal to the bore of said chamber.

B, C represent the inlet and outlet pipes whereby the 'gasolene or other liquid to be filtered or strained is conducted into the separating chamber and drawnfoil therefrom. These pipes are connected with the .upper part of the separating chambervand preferably arranged horizontally inline and diametri'cally opposite each other. The connection between these pipes and the separating chamber may be effected in various ways, the means, shown in the drawings, for this purpose being preferred and consisting of inlet and outlet coupling nipples D, E,which receive the inlet and outlet pipes, respectively, and having inner screw threaded ends d, e which engage with threaded openings in opposite sides 'of the separating chamber, and outer threaded ends d1, e1 which receive the packing nuts f, f1 of the stuiiing boxes whereby-.tight joints are produced between the coupling nipples and the inlet and outlet pipes. V

The nipple ofthe inlet pipe preferably terminatesiushnor nearly-so with-the inner side of the separating chamber but the nipple of rating chamber to the outlet pipe.

the delivery or outlet pipe beyond the inner side o the separating chamber and serves as part of the means for supporting the screen whereby the liquid is projects inwardly` filtered or strained in passing from the sepa- This screen is preferably constructed of Woven wire, gauze or other :foraminous material in the form 'ofi a cylindrical body G having a semi-spherical head -g at one end. The opposite end of the body of the screen is secured lto a coupling sleeve H which has a screw connection with the inner end of the outlet nipple E. In the assembled position of the parts the' screen is arranged horizontally with its body in the upper part of the separating chamber and axially in line with the inlet and outlet pipes and with its head adj a# cent to the inlet nipple.

W'hen the iilter or strainer is in use the liquid passes from the inlet pipe into the separating chamber, thence through the. screen and out through the outlet pipe. As the liquid enters the separating chamber from the inlet pipe any heavy impurities contained therein are separated therefrom by gravity and c'ollect on the bottom of the separating chamber from which the sediment may be removed or drained oli' from time to time by a blow-off valve or drain cocki connected with the bottom of the separating chamber. As the liquid passes through the screen any light im'- purities, such as Athreads and small leces of straw or wood, are separated t erefrom which impurities may be remo ved from time to time, access for this purpose being had to the interior of the separating chamber by ref moving the cover at the upper end thereof. By constructing the screen of tubular form having a body and head of the same material a very large separating surface is produced which` is not likely to become wholly clogged by accumulations of light imnecessary.

I claim as my invention: 1. A liquid filter com rising a separating IOO chamber, inlet and out et pipes each connected with said chamber by a nipple which screws into an opening in the side' of the chamber while its outer end receives thle res ective pipe, and a packing nutapplied to t e'outer end of said nipple and around said pipe, and a screen arranged over tlie outlet` selnisplieiical head at one end,and aeoupf nipple Within the separating chamber, subi ling sleeve Whcll'lias asclewoonnection with stantielly as sethforth. v l the inner end ofthe nipple of the outlet pipe 2.
